Change-aware preemption prioritization

Successful software evolves as developers add more features, respond to requirements changes, and fix faults. Regression testing is widely used for ensuring the validity of evolving software. As regression test suites grow over time, it becomes expensive to execute them. The problem is exacerbated when test suites contain multithreaded tests. These tests are generally long running as they explore many different thread schedules searching for concurrency faults such as dataraces, atomicity violations, and deadlocks. While many techniques have been proposed for regression test prioritization, selection, and minimization for sequential tests, there is not much work for multithreaded code.
